Klass and Ning are the perfect hosts. Fast responsive, had useful suggestions to all our questions, it was a great pleasure to deal.
The apartment was clean and spacious as we expected, comfortable beds and so on, we did not miss there anything in the apartment. Ever were offered welcome drinks upon arrival :-)
Considering in mind that there is not really clear where the center of Bangkok is, the location was really good. Easy to get a taxi, 7-eleven just downstairs, places to have a diner on a walking distance.
We had a late flight home, Klass offered to us a free service to store our luggage after we checked out.
In fact we had a pleasure to satay and we would repeat it any day again. :-)
